How To Install Webmin on Ubuntu 22.04 LTS

In this tutorial, we will show you how to install Webmin on Ubuntu 22.04 LTS. For those of you who didn’t know, Webmin is an open-source web-based Linux system administration control panel. It is based on Perl and uses port number 10000 to let users access the web GUI dashboard for managing various server services, configuration files, disk quotas, and many more.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Webmin web-based interface systems administration on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

• A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Webmin on Ubuntu 22.04 LTS Jammy Jellyfish

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install vim apt-transport-https curl wget software-properties-common

Step 2. Installing Telegram Desktop on Ubuntu 22.04.

By default, Webmin is not available on Ubuntu 22.04 base repository. Now run the following command below to add the Webmin PPA repository to your Ubuntu system:

sudo add-apt-repository "deb https://download.webmin.com/download/repository sarge contrib"

Next, import the GPG key:

wget https://download.webmin.com/jcameron-key.asc cat jcameron-key.asc | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/jcameron-key.gpg >/dev/null

After the repository is enabled, now install the latest version of Webmin using the below command:

sudo apt update
sudo apt install webmin

Once is done, let’s first check whether the service of Webmin is running in the background without any error:

sudo systemctl status webmin

Step 4. Configure Firewall.

If you are using UFW (Uncomplicated Firewall), you need to configure it to allow access to ports 10000 for the server to work:

sudo ufw allow 10000

Step 5. Accessing Webmin Web Interface.

Once successfully installed, open a web browser on your system and type the server’s IP in the address bar. You will get the default Webmin page:

https://your-server-ip-address:10000

If pop up SSL certificate error, to bypass that, click on the Advanced button and then on “continue to your-server-IP”. To log in, enter your system username and password using an account with root privileges.

Step 6. Enable SSL on Webmin.

By default, Webmin is configured to use a self-signed certificate. So it is recommended to secure Webmin with a trusted SSL certificate. Now we install Apache and Certbot to your system:

sudo apt install apache2 certbot python3-certbot-apache

After installation is complete, Start the Apache service and enable it to start at system reboot with the following command:

sudo systemctl start apache2
sudo systemctl enable apache2

Next, on the Webmin interface, click on your Networking -> Network Configuration then click on the Hostname and DNS. You should see the following screen:

Then, click on the Webmin -> Webmin Configuration. You should see the following screen:

Finally, click on SSL Encryption. Provide your domain name in the Hostnames field, Provide your website root directory in the Other directory fields, and click on the Request Certificate button to install the certificate. You should see the following screen:
